Technical Evaluation of the Faccin HAV 3145
3-Roll Variable Geometry Plate Bending Roll (Year 2017)
1. Technical Evaluation Overview
The Faccin HAV 3145 is a 3-roll variable geometry plate bending roll designed for forming metal plates up to a stated maximum plate width of 120 inches. The machine is equipped with hardened and polished rolls, which are relevant to surface finish consistency and wear resistance.
The reported top roll diameter of 17.72 inches and side roll diameters of 15.75 inches indicate a configuration suitable for handling relatively thick plates within the stated capacity ranges.
Forming performance is specified at two material strength levels. At 37.7 KSI, the machine is rated for 1.58 inches bending thickness with an 89-inch internal diameter, and 1 inch pre-bending thickness with the same diameter. At 52.2 KSI, capacity is reduced to 1.34 inches bending thickness at an 8-inch internal diameter, and 0.8 inches pre-bending thickness with an 89-inch internal diameter.
The stated maximum rotation speed of 23 ft/min defines forming throughput limits. A Siemens control system is installed, but no specific model, software version, or axis configuration is provided. The listed 3336 PSI bending force on the top roll reflects available forming pressure but does not, by itself, define overall forming capability without additional hydraulic details.
2. What to Check Before Buying
Because several technical details are not specified, a physical and functional inspection is essential. Mechanically, the rolls should be checked for surface wear, scoring, or diameter deviation, as hardened rolls can still suffer from localized damage if previously overloaded. Roll alignment and bearing condition should be verified under load.
Hydraulic components require inspection for pressure stability, leakage, and smooth response, especially since only the top roll force is stated and pump or valve specifications are not provided.
Electrically, the Siemens control should be powered and tested to confirm proper operation, parameter access, and error history. Verification of control software version, backup availability, and I/O functionality is recommended, as these details are not listed. Safety circuits, emergency stops, and limit switches should also be confirmed to be operational and compliant with current standards.
3. Typical Industrial Applications
Based on the provided capacities, this type of 3-roll variable geometry plate roll is suitable for forming cylindrical or conical shells from medium to heavy plate materials within the stated thickness and strength limits. Typical applications include rolled components for structural fabrications, pressure vessel shells, tanks, and heavy industrial assemblies, provided that material grade and dimensions remain within the documented forming ranges. Use outside these limits should not be assumed without verification testing.
4. Common Risks in Used Machines
For used plate rolls, common risks include uneven roll wear leading to inconsistent curvature, hidden fatigue in hydraulic components, and reduced accuracy due to frame or roll alignment issues. Control systems may present risks related to outdated software, unavailable backups, or undocumented parameter changes. Documentation gaps—such as missing electrical diagrams or hydraulic schematics—can complicate troubleshooting and future servicing.
5. Maintenance and Service Considerations
Maintenance requirements depend heavily on the actual operating history and condition of the machine. Regular inspection of roll surfaces, lubrication points, and hydraulic seals is critical. The Siemens control should be evaluated for long-term supportability, including availability of replacement components and technical documentation. Since no service records or maintenance intervals are provided, verification of past service history and confirmation of spare part accessibility should be considered essential before long-term operation.
Final Note:
Several important details—such as total installed power, hydraulic system specifications, control model/version, and machine weight—are not provided. These should be verified directly on the machine or through original documentation before any technical conclusions are finalized.
